Haptic transmission method and mobile terminal for same

Abstract

The present invention relates to a haptic transmission method. The haptic transmission method includes the steps of: a mobile terminal at a transmitting side displaying a screen capable of receiving an input for a receiver; when an input of selection for the receiver is completed, displaying a screen capable of receiving content to be transmitted; and when an impact or a touch input is detected after the screen display, generating a vibration pattern signal on the basis of the detected impact or the detected touch input and transmitting a message including the vibration pattern signal.

The invention claimed is: 
     
       1. A haptic transmission method by a transmitting side mobile terminal, comprising:
 displaying a screen for receiving an input of a receiver; 
 when an input for selecting the receiver is completed, displaying a screen for receiving an input of content to be transmitted; 
 determining whether a receipt notification has not been received from the receiver after transmitting a message to the receiver; 
 providing a first vibration, to the transmitting side mobile terminal, indicating the receipt notification whenever the receipt notification is received; 
 determining whether the transmitting side mobile terminal is in a holding state in a hand of a user using a proximity sensor whenever the receipt notification has not been received; 
 detecting an impact or a touch input corresponding to shaking the transmitting side mobile terminal by activating an acceleration sensor or a gyro sensor whenever the receipt notification has not been received and the transmitting side mobile terminal is in the holding state; 
 generating a vibration pattern signal on the basis of the detected impact or the detected touch input when the impact or the touch input is detected whenever the receipt notification has not been received; and 
 providing a second vibration, to the receiver, corresponding to the vibration pattern signal by transmitting a message including the vibration pattern signal to the receiver, 
 wherein the detected impact or the detected touch input is a shaking pattern and a shaking intensity. 
 
     
     
       2. The method of  claim 1 , wherein an indicator for emoticons is displayed on the screen for receiving an input of content to be transmitted,
 wherein when the indicator is touched, a plurality of emoticons are displayed, and 
 wherein when an input for selecting a specific emoticon among the plurality of emoticons is received, a vibration pattern signal is generated based on the specific emoticon. 
 
     
     
       3. The method of  claim 2 , wherein when an input for selecting the specific emoticon is received, an indicator for adjusting a vibration tempo and a vibration intensity according to the emoticon is displayed, and
 wherein when a user inputs one of the vibration tempo and the vibration intensity, a vibration pattern signal is generated based on the adjusted tempo and intensity, and then is transmitted. 
 
     
     
       4. The method of  claim 1 , wherein the impact detection is performed by detecting an impact occurring when a user's knock is detected on a front surface, a rear surface or a side surface of on the transmitting side mobile terminal, and
 wherein the user's knock is detected by measuring acceleration between consecutive knocks. 
 
     
     
       5. The method of  claim 1 , wherein in the step of generating a vibration pattern signal on the basis of the touch input, whenever numeric keys or text keys are consecutively input, a vibration pattern signal corresponding to each of the input numeric or text keys is generated. 
     
     
       6. The method of  claim 5 , wherein in the step of generating a vibration pattern signal corresponding to each of the input numeric or text keys, a different vibration pattern signal is generated according to whether an input text key is a consonant or a vowel, or a different vibration pattern signal is generated according to a position of an input text key on a keypad, the position indicating a row and a column. 
     
     
       7. The method of  claim 1 , wherein after displaying the screen for receiving an input of content to be transmitted, whether a user's facial expression has changed or not is sensed by a camera, and
 wherein a vibration pattern signal indicating a user's feeling is generated according to the change of facial expression, and is transmitted. 
 
     
     
       8. The method of  claim 1 , wherein the first vibration indicating that the receiver is writing a response message. 
     
     
       9. The method of  claim 1 , wherein generating the vibration signal is performed when the shaking intensity is greater than a threshold value in order to distinguish a general shaking occurring in a portable state from the shaking pattern. 
     
     
       10. The method of  claim 1 , wherein the shaking pattern comprises information on pitch, roll and yaw and information on a frequency. 
     
     
       11. A mobile terminal, comprising:
 a touch screen configured to display a screen for inputting a receiver, and configured to display a screen for inputting content to be transmitted when an input for selecting the receiver is completed; and 
 a controller, configured to:
 determine whether a receipt notification has not been received from the receiver after transmitting a message to the receiver, 
 provide a first vibration, to the transmitting side mobile terminal, indicating the receipt notification that whenever the receipt notification is received, 
 determine whether the transmitting side mobile terminal is in a holding state in a hand of a user using a proximity sensor whenever the receipt notification has not been received, 
 detect an impact or a touch input corresponding to shaking the transmitting side mobile terminal by activating an acceleration sensor or gyro sensor whenever the receipt notification has not been received and the transmitting side mobile terminal is in the holding state, 
 generate a vibration pattern signal on the basis of the detected impact or the detected touch input when the impact or the touch input is detected whenever the receipt notification has not been received, and 
 provide a second vibration to the receiver corresponding to the vibration pattern signal by transmitting a message including the vibration pattern signal to the receiver, 
 wherein the detected impact or the detected touch input is a shaking pattern and a shaking intensity. 
 
 
     
     
       12. The mobile terminal of  claim 11 , wherein the impact detection is performed by detecting an impact occurring when the transmitting side mobile terminal is shaken. 
     
     
       13. The mobile terminal of  claim 11 , wherein the impact detection is performed by detecting an impact occurring when a user knocks on the transmitting side mobile terminal. 
     
     
       14. The mobile terminal of  claim 11 , wherein in the step of generating a vibration pattern signal on the basis of the touch input, whenever numeric keys or text keys are consecutively input, a vibration pattern signal corresponding to each of the input numeric or text keys is generated. 
     
     
       15. The mobile terminal of  claim 14 , wherein in the step of generating a vibration pattern signal corresponding to each of the input numeric or text keys, a different vibration pattern signal is generated according to whether an input text key is a consonant or a vowel, or a different vibration pattern signal is generated according to a position of an input text key on a keypad, the position indicating a row and a column.
